Combined blood and brain tests predict risk of stroke recurrence

A blood test and a brain scan could help people at risk of intracerebral haemorrhage (ICH)

Edinburgh University researchers have found combining the two tests for patients who have suffered a stroke could help predict the chances of them experiencing a second stroke. They said the new approach could revolutionise the way doctors manage strokes caused by brain bleeding, known as intracerebral haemorrhage (ICH).

The team, led by Mark A Rodrigues with the Centre for Clinical Brain Sciences at the University of Edinburgh in Scotland, published findings online Jan. 10 in Lancet Neurology. “We aimed to develop a prediction model for the identification of cerebral amyloid angiopathy (CAA)-associated lobar intracerebral hemorrhage using CT features and genotype,” Rodrigues et al. wrote.

The scientists used the blood test and brain scan images to detect cerebral amyloid angiopathy (CAA), which is caused by a build-up of a protein known as amyloid in the walls of blood vessels in the brain. CAA can cause ICH and is linked to a higher risk of further strokes and dementia.

The researchers used computed tomography (CT) scans in more than 100 patients who died following their first ICH.
